Tonight, putin's aides are denying he stole a diamond encrusted super bowl ring from new england patriots owner robert kraft. The two met in 2005. Both sides agree that kraft showed him his super bowl bling, reportedly worth over $25,000. They also agree that putin left with it. Kraft issued a statement at time, saying he gave putin the ring as a gift. A sign oriendship with the russian people. But on thursday, kraft revealed what he said is the real truth. He says he handed putin the ring to look at and remembers the former kgb spy saying, "i could ski kill someone with this ring." Then, according to kraft, the russian president pocketed it. All 4.94 carats. All 124 diamonds. Kraft says he called it a gift only after pressure from the white house. Today, the kremlin is pushing back.
